For example, learning-disabled children often have lower levels of processing speed, thus the GAI is an acceptable scoring alternative to the usual method which does take memory and processing speed into account when norming the results.
Discuss the main uses for the WAIS-IV and WISC-IV
All forms of the Wechsler Intelligence Scales are standardized tests, "meaning that as part of the test design, they were administered to a large representative sample of the target population, and norms were determined from the results" (Encyclopedia of Children's Health, 2010). All IQ tests are limited in their ability to describe the individual's full range of ability and should be used in conjunction with other measures. However, the inclusion of the performance section in the Wechsler scales is especially helpful in assessing the cognitive ability of non-native speakers and children with speech and language disorders. "The test can be of particular value to school psychologists screening for specific learning disabilities because of the number of specific subtests that make up each section" that relate to various types of information processing (Encyclopedia of Children's Health, 2010).
Give an explanatory outline of the successive-level interpretation procedure for interpreting WAIS and WISC test data.
Level I: Interpret full-scale IQ -- a generalized summary of the results as a whole
Level II: Interpret...
